如何解析包含混合字符串和数字的 JSON object 的一部分？

Question

I have a JSON file that was processor generated with lines like this

jsonData:   "{data: [350.23,250.32,150.34,340.50,236.70,370.45,380.55]}"

I can target the 'jsonData' object but that returns everything within the double quotes as a string. I tried...dataset[0].jsonData[8] which returns the '3' from the first value. I guess I could throw the mixed strings into a JS function and use regex to remove the extra stuff, but thats probably the hackyest way to do this.

Whats the easiest way to target the values only?

Answer 1

If you don't want to spend the time fixing your JSON just do this:

let values = "{data: [350.23,250.32,150.34,340.50,236.70,370.45,380.55]}".split(',').map(_ => _.replace(/[^0-9.]/g,''))

console.log(values)

Answer 2

If you want to interact with it like the list I would consider something like

var list = jsonData.split("[")[1].split("]")[0].split(",")

Console.log(list);

The console reads:

[
  '350.23', '250.32',
  '150.34', '340.50',
  '236.70', '370.45',
  '380.55'
]

From here you can use list[3] to get 340.50
